BMW M4 and M4 GTS Tuning Software from CarBahn. Stage 1 Tune up to 549 HP, Stage 2 up to 585 HP, Stage 3 up to 613 HP. CarBahn Competition performance upgrades are are designed to deliver the highest safe output possible. Smooth Power means software tuned correctly, not over-tuned. Excessive torque will break the tires loose, break the engine and drive train. Managed torque with a smooth delivery makes the car easier to drive thereby faster and more reliable. Most if not all our competitor tunes attempt to run too much boost, resulting in active knock corrections which causes surging during acceleration. Our Stage 1 and Stage 2 Power Packages includes track-tested upgrade components to complement the added horsepower for your enjoyable driving experience.
NOW AVAILABLE – Stage 3 Tuning Software up to 613 HP.
